I have to say in Texas the 6th gear is fine. That's at 75 MPH. Now if I want to get to 90 MPH i would go to 4th. Coming from a fusion back to a mustang has been great. The fusion also would have shifted from 6th to 4th to make the same move. Yes I'm spoiled as all roads arond here are 70+ outside of town in any direction.
Side note punched the V6 passing today. At 45 MPH I shifted into 2nd, got a 3rd (traction control kicked in) and caught a small tire spin going from 3rd to 4th. Happy has a Camel on hump day.
